Signal level dbm wifi

Ultimately, the easiest and most consistent way to express signal strength is with dBm, which stands for decibels relative to a milliwatt. Since RSSI is handled.

Wireless signal strength is measured in dBm (decibel milliwatts) and is, somewhat confusingly, expressed only as negative values. Maximum signal strength, you are probably standing right next to the access point.

Anything down to this level can be considered excellent signal strength.

SNR is not actually a ratio but the difference in decibels between the received signal and the background noise level (noise floor).
